OLARNOE RATHBONE, OF ALBANY, NEV YORK, ASSIGNOR TO THE RANSOM STOVE COMPANY, OF SAME PLACE.

COOK-STOVE.

SPECIFICATION forming part of Letters Patent No. 385,135, dated June 26, 1888.

Application tiled April 13, 1886.

. the width of the stove at the back ofthe oven iro and provided with a reservoir for hot water.

The object of my improvements is to provide asuitable damper for the flue at the back of the oven,so that the currents of heat can be diverted from a direct downward course and forced to pass into the iiue beneath the reservoir to more edectually heat the water therein, from whence they re-enter the iue at the back of the oven to continue their course around the oven.

In the accompanying drawings, which are herein referred to and form part of this specification, Figure lis aperspective view of part of the rear of a stove provided with my improvenients, with the side plate removed to show the internal parts, the damper being turned to direct the drafts from a direct downward course; Fig. 2, a like view with the damper turned to permit the heat-currents to pass directly down the iiue at the back of the oven; and Fig. 3 an enlarged and detached perspective view of my damper.

As represented in the drawings, A is the body of the stove; B, the oven; O, flue over oven; C',1lue at back of oven, and C2, flue under oven; D, water-reservoir; E, opening from voir, and F a damper for the opening into the reservoir'chamber.

The body A of the stove may be made in any preferred form and may be provided with any desired form of hre-chamber. The lues around the oven B, but especially the one` at the back of the oven, should be in the form commonly known as sheet-t1ues, which are not divided by flue-strips intoa series of upcast7 and downcast iiues.

The opening E (which communicates from the iue C at the back of the oven into the chamber D', which contains the water-reservoir D) is made near the bottom of said reservoir-chamber andextends nearly across the width of the flue C'.

Serial No. 198.700. (No model.)

The damper F, which is a single piece, is divided lengthwise into the two sectionsf and f',of about equal length, the first of which is 55 aat plate of sufficient width to close the height of the opening E, and when turned in the proper direction to reach diagonally across the flue C to shut ott the passage through the latter. Said plate is provided at 6r each end with a trunniomfz, on which it rocks, and one of said trunnions projects through the side of the stove to form a` handle by which said damper is operated. The partf' of said damper is made in the form of a segment of a cylindrical shell with its convex surface uppermost, and its concave part will form a hollow pocket,which, when the damper is turned down in the position shown in Fig. 1,will afford a free communication from the 7o i-nterior of the reservoir chamber into the lower part of the liuc C', and at the same time it will close the direct passage through that half of the flue C', so that the draft-currents descending through said flue will be defected from their direct course, and, passing into the reservoirchamber D', are carried circuitously through said chamber and reenter the iue O' below the damper F through the opening formed by the hollow pocketf'. The course oi' 8o the draft-currents, when said damper is turned in the position shown in Fig. 2, is indicated Vhen the damper F is turned in the direction shown in Fig. 2, it will close the opening E and leave an S5 unobstructed passage through the iiue O', so that the draft-currents will pass directly down through said iiue, as indicated by the arrows in said figure.

I claim as my inventionb- 9o In a coolestove, the combination of a single flue, G', at the back of the oven, a reserv`oirchamber, D', having an opening, E, which forms a communication between said ue and chamber, and a rolling damper, F, provided with a segmental pocket, j", as and for the purpose herein specified.
